Shows exactly which container patterns matter and how to use them: use named volumes for host-agnostic persistent storage, create user networks for automatic DNS service discovery, run dive to inspect layer sizes, run hadolint and trivy in CI to catch Dockerfile mistakes and CVEs, and mount the docker socket (docker-from-docker) to reuse host cache instead of true DinD. Covers dockerignore to speed builds, deterministic image digests versus tags, and using an exec-style entrypoint so the real app becomes PID 1.
